A girl named Karana was alone on an island when a ship came to the island and took her people. She stayed on the island so she could be with her brother, but he was killed by wild dogs/foxes.
As she hauled the whale bones back to where she would build a shelter, the wild dogs watched her do so.
She started to work with her whalebones that she hauled from the shore of the beach and used kelp to bind the ribs together. She would have used seal sinew but the dogs would like it and knaw on it and get through.
